2,000-year-old stellar mystery solved

Astronomers finally know why the first documented supernova was super-sized.
The exploded star was observed by the ancient Chinese
in the year 185, and visible for eight months.
It was later found to be a bigger-than-expected supernova remnant,
8,000 light years away.

Fine and good. The Chinese did see the supernova in 185 CE.

But how about sightings in other cultures of that time ?
I found images of a pictograph of a supernova (?) by the Anasazi
in the Four Corners area of the US, but that was in the 1200's CE
I've also seen one reference to cave drawings in Guam, but no date.

Wouldn't you think more cultures would have left evidence
of this or other supernovae events ?
